I would pay more for a solenoid that reversed the magnet to pull the piston up and down and not rely on a spring loaded piston. Not sure if this exists but if all solenoids are built using a spring they will suffer from this problem at some point. The electronics are not very complex to turn on and off a magnet, to me the spring is the weak link in the design.
